Control of Signal Processing Algorithms using the MATRIX Interface

This paper describes the MATRIX (Multipurpose Array of Tactile Rods for Interactive eXpression) interface and its use as a controller for several signal processing algorithms (e.g., delay, reverb, EQ, and chorus). Although these algorithms are conventional effects, the multi-parameter control provided by the MATRIX allows users to manipulate audio in a manner that was not previously feasible.
